SEAT POST ASSEMBLY Filed Sept. 13, 1957 INVENTOR SAMUEL A.SNELL ATTORNEY Patented Apr. 23, 1940 UNITED STATES SEAT POST ASSEMBLY SamuelA. Snell, Toledo, Ohio, assignor to The,

American-National Company, Toledo, Ohio, a

corporation of Ohio Application September 13, 1937, Serial No. 163,670

8 Claims.

This invention relates generally to saddle mountings for use withjuvenile vehicles such as veloolpedes, bicycles, and the like andconstitutes a continuation-impart of my application filed July 12, 1937,hearing Serial No. 153,143.

One of the essential objects of the invention is to provide a saddlemounting of this type wherein provision is made for adjusting the saddlelengthwise of the backbone as well as in a direction at substantiallyright angles thereto so that the rider may be positioned correctlyrelative to the pedals of the vehicle.

Another object is to provide a mounting wherein the saddle may beeffectively held against movement in either of the two directionsmentioned relative to the backbone by the clamping action of a singlenut on the supporting post for the saddle.

Other objects, advantages and novel details of 0 construction of thisinvention will be made more apparent as this description proceeds,especially when considered in connection with the accompanying drawing,wherein:

Figure l is a side elevation of a velocipede pro- 5 vided with a saddlemounting embodying my invention;

Figure 2 is a rear elevation of the velocipede;

Figure 3 is a vertical sectional view taken substantially on the line3--3 of Figure 1;

0 Figure 4 is a fragmentary perspective view of a slightly modifiedconstruction;

Figure 5 is a vertical sectional view taken substantially on the line 55of Figure 4.

Referring now to the drawing, A is the front wheel, B is the rear wheel,and C is the front fork straddling the front wheel and having anupwardly extending tubular shank I. D is an axle for the front wheeljournaled in the furcations of the fork C and provided at its oppositeends 0 with cranks E! and pedals F. G is the backbone having a pair oflaterally spaced strips 2 and 3 of spring steel that are terminallyconnected to the shank l of the front fork and to the axle H for therear wheel B.

s The saddle M is movable lengthwise of the backbone G and is alsomovable in a direction at substantially right angles thereto to positionthe rider properly relative to the pedals F. As shown, the saddle M hasa seat 4 provided with spring 0 structure 5 mounted on a substantiallyhorizontal arm 6 of a supporting post 1. In the present instance thepost 1 is provided at its lower end with exterior threads 8 and extendsdownwardly between the strips 2 and 3 of the backbone. For

5 carrying this post 1 there is a flanged bracket 9 slidable on thebackbone and having an interiorly threaded bushing Ill receiving thepost 1 and engaging the threads 8 thereof. A cooperatingplate II issleeved on the post beneath the backbone G, and a nut 12 threadedlyengages 5 the post 1 beneath the plate I l. Thus, when the nut I2 isloosened, the bracket 9 and plate ll assembly may be moved along thebackbone G to the desired position and/or the post 1 may be revolved inthe bushing ID to raise and lower the 19. seat 4 relative to thebackbone G. When the nut I2 is tightened, the saddle M will beeffectively held against both sliding and rotary movements.

In Figures 4 and 5 I have illustrated a slight modification in which thebackbone 40 comprises a single strip of spring steel instead of thelaterally spaced strips such as 2 and 3, and the supporting post 4| forthe seat extends downwardly through a hole 42 in this backbone.Preferably the bushing 43 threadedly engaging the post 4| is on top ofthe backbone 40 over the hole 42 and has a depending tubular portion 45that extends through and has its lower edges upset against theloweredges of said hole. A flanged clamping plate 46 is sleeved upon thepost 41 beneath the backbone and a clamping nut 41 threadedly engagesthe post beneath the plate 46. Thus, when the nut 41 is loosened, thepost 41 may be revolved in the bushing 43 to raise and lower the seatrelative to the backbone 40. When the nut 41 is tightened, the seat willbe effectively held against turning movement. In this connection it willof course be apparent that a mounting of this type may be employed withany single strip, bar, rod or tube type of backbone.

What I claim as my invention is:

1. In a saddle mounting, a backbone, a member embracing said backboneand slidable lengthwise thereof, a bushing rigidly carried by saidmember, a seat post threadedly engaging said bushing to be verticallyadjustable therein, and clamping means carried by said post for holdingsaid member and. post in adjusted position.

2. In a saddle mounting, a backbone having laterally spaced portions, amember embracing said backbone to be longitudinally adjustable thereon,said member being provided with an internally threaded portion, athreaded seat post engaging the threaded portion of said member andextending between the spaced portions of said backbone, and a clampingnut engaging the lower portion of said post, whereby said post may bevertically adjusted in said member and 55 together with said nut forms aclamping means for securing said member to said backbone.

3. In a saddle mounting, a backbone formed of a pair of laterally spacedstrips, a member embracing said strips to be longitudinally adjustablethereon, a seat post extending between said strips and threadedlyengaging said member to be vertically adjustable therein, and a clampingnut engaging the threaded portion of said post.

4. In a saddle mounting, a backbone, a bracket slidable upon thebackbone, an interiorly threaded bushing anchored in said bracket, aseat post having exterior threads engaging the interiorly threadedbushing and rotatable therein, a cooperating plate sleeved on said postbeneath said backbone, and a nut threadedly engaging the post beneathsaid plate, the arrangement being such that said nut cooperates withsaid bracket, post and plate to hold said parts against movementlongitudinally of the said backbone and cooperates with said plate andpost to hold the latter against turning movement.

5. In a saddle mounting, a backbone comprising a pair of laterallyspaced elongated frame members, a bracket slidable upon the backbone andhaving an opening registering with the space between said laterallyspaced frame members, an interio-rly threaded bushing anchored in saidbushing, a seat 'post having exterior threads engaging the interiorlythreaded bushing and rotatable therein, a plate sleeved on said postheneath said backbone, and a nut threadedly engaging the post beneathsaid plate, the arrangement being such that said nut cooperates withsaid bracket, post and plate to hold said parts against movementlongitudinally of said backbone and cooperates with said plate and postto hold the latter against turning movement.

Bl In a saddle mounting, a backbone, a member embracing said backboneand adjustable longitudinally thereof, a bushing carried by said member,a seat post adjustable in said bushing, a member sleeved on said postbeneath said back bone, and a clamping element adjustable on said postbeneath and engageable with said sleeved member.

7. In a saddle mounting, a backbone having a pair of laterally spacedportions, a member embracing said portions and adjustable longitudinallythereof, a seat post between said portions and adjustable in saidmember, a cooperating member sleeved on said post beneath said spacedportions within the embrace of the member aforesaid, and a clampingmember adjustable on said post beneath and engageable with saidcooperating member.

8. In a saddle mounting, a backbone, a bracket slidable upon saidbackbone, a bushing fixed to said bracket, a seat post adjustable insaid bushing, a clamping plate sleeved on said post beneath saidbackbone and engageable with'the latter, and a nut adjustable on thepost beneath said plate, the arrangement being such that said nutcooperates with said bracket, post and plate to hold said parts againstsliding movement on the backbone and cooperates with said plate and postto hold the latter against turning movement.
